Datasets:
Audio and text columns are misaligned - most rows pair the wrong sentence (verified by transcription)

We trained a Piper TTS voice on this dataset and got unintelligible output despite healthy training metrics, so we audited the pairing directly: we transcribed all 6,892 clips with Whisper large-v3 and compared each transcript against the texts shipped in the dataset.
Findings:
- Only 1,323 of 6,892 rows (19%) have audio that matches the text in their own row. Those correct rows sit in the first ~44% of the file; after that, essentially no row matches.
- For the remaining ~81%, the correct sentence is not merely in a different row - it does not appear anywhere in the dataset's text column. Example: distinctive words from a story the female speaker reads (e.g. ਕਿਸਮਤ) occur in 0 of the 6,892 provided texts.
- Concrete example, second row of the train split as distributed: the text column reads "ਇਕ ਤਾਂ ਨਵੀਂ ਇਸ ਗੱਲੋਂ ਕਿ ਉਹ ਆਪਣੇ ਖ਼ਾਵੰਦ ਦੀ ਦੂਸਰੀ ਬੀਵੀ ਹੈ..." while the audio in the same row says "ਕਾਰਣ ਐ ਕਿ ਮੈਂ ਤਾਂ ਹਾੜੇ ਨਾਲੋਂ ਵਕਰੀ ਕਿਸਮਤ ਦੇ ਵਡਿਆਈ ਗਈ ਹਾਂ" - a sentence from a different story.
This looks like the audio and text lists came from two different subsets of the IndicTTS corpus when the parquet was built. The audio itself is fine - it's the pairing that's broken.
Could you publish a corrected version, or the original filename-to-transcript mapping from the IndicTTS release? We can share our full per-row transcription file if it helps verify or rebuild the pairing.
